Title: Ultrasonic flowmeter
Inventor: SOEJIMA JUNICHIRO
IPC: G01F1/66
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To obtain an ultrasonic flowmeter which increases the measured value of a propagation time difference and whose measuring precision is enhanced by a method wherein a rectangle which has a long side in the propagation direction of ultrasonic waves is selected as the cross-sectional shape of the flow passage of a fluid and round parts are formed in flour corners of the rectangle. SOLUTION: The cross-sectional shape of a conduit P is formed as a rectangular shape, and its long sides are parallel to the propagation direction of ultarsonic waves formed between a pair of transducers T1, T2. In addition, round parts which are used to prevent the generation of vortexes are formed in four corners of the conduit P. Ultrasonic waves which are radiated from the transducer T1 or T2 are propagated in a fluid which flows inside the conduit P at an average flow velocity V, and they are then received by the transducer T2 or T1 on the other side. Then, the mean flow velocity V and a flow rate inside the cross section of the conduit P are computed on the basis of the measured value of a propagation time difference in every propagation direction.  In this manner, since the cross-sectional shape of the conduit P in a rectangular shape which comprises long sides in the propagation direction of the ultrasonic waves, the large propagation time difference of the ultrasonic waves is obtained at a set flow rate, and the measuring precision of an ultrasonic flowmeter is enhanced.

Abstract: PURPOSE:To simplify considerably the operation for adjusting a rod for adjusting the decelerating position conforming to the thickness of dies determined from the displacement of a moving platen in the stage of exchanging the dies by calculating the adequate length of said rod and sliding the rod. CONSTITUTION:The displacement of a moving platen 3 with respect to a stationary plate 1 detected by the 1st linear scale sensor 20 upon completion of mating of upper and lower dies 5, 6 is converted to a die thickness H by the die thickness conversion circuit of a microcomputer 30. The output from said circuit is inputted to an arithmetic circuit for a rod length where the adequate effective length L1 of a rod 13 for adjusting the decelerating position conforming to the thickness H is calculated. On the other hand, the present effective length L2 of the rod 13 in the stage of mating the dies is detected by the 2nd linear scale sensor 23 and is preliminarily stored. The difference between the lengths L1 and L2, i.e., the extent of the movement of the rod 13 necessary for obtaining the length L1 is calculated by the arithmetic circuit. A servocontrol motor 33 is actuated by the operation of a data input device 25 and the effective length of the rod 13 is adjusted to attain the length L1.

IPC: G03G15/09
Filed: 1986-07-03
Abstract: PURPOSE:To preclude blocking without applying any mechanical stress to a developer by providing an electric field curtain for developer layer thickness control opposite to a developing sleeve and reversing the developer conveyance direction of the electric field curtain opposite and the moving direction of the developing sleeve. CONSTITUTION:An AC voltage is applied from a power source 7 to an insulator substrate 5a where electrodes 5b are arranged in parallel to form an electric field curtain which produces a progressive waveform crossing electric field on the plane of the substrate. The interval between the substrate and a developing sleeve 2 is set to about 0.5-4 times the pitch of the electrodes 5b. Upper layer particles in a developer particle layer 3 which is conveyed by the sleeve 2 as shown by an arrow beta are pushed back by the electric field curtain, so as uniform thin layer particle group is conveyed to the development part of a photosensitive body 1 to perform stable development. Therefore, no mechanical stress is applied to the developer particles and even a constant pressure developer and a lor-fusion-point developer which easily cause blocking are usable with reliability.

IPC: G01M10/00
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To measure sound generated from various test pieces placed into water current of a passed water tank by separating the sound from background noise in high sensitivity. SOLUTION: Sound wave generated from a test piece 51 passes through water in a measuring cylinder 40 and an acoustic window 41 and reaches a plurality of hydrophones 48 disposed in plane. Phase difference of a sound wave signal obtained by respective hydrophones 48 is used and the respective signals are superposed to provide directivity and the sound wave is collected in wide angle. As the sound wave transmitted to background of the plurality of hydrophones 48 is absorbed into noise absorption material 46 of a sound absorption trough 42, reflected wave reflected from an inner wall of the noise absorption trough 42 is absorbed and the sound wave is measured at high S/N ratio.  Unnecessary sound wave is removed when the sound absorption material 46 is formed with wedge type of cellular rubber and mounted at space of half wave length λN/2 of the sound wave to be absorbed along water current direction, so that the sound wave can be measured at high S/N ratio.

Title: Intaglio printing plate and printing method
Inventor: MATSUMOTO KATSUTOSHI
IPC: H05K3/06
Filed: 1979-12-03
Abstract: PURPOSE: To prevent ink from overflowing by a method wherein an oil rejecting layer is installed on an elastic body layer and at least one layer of the layer concerned is notched and further, an eliminated ink pool part is installed.  
     CONSTITUTION: A transfer ink Ia comes to contact with a printing plate C through an ink supplying roller Aa and an ink applying roller Ab. The surface of the printing plate C is constituted with a peak part of an oil rejecting layer Ca and a bottom part of an ink capacitance Cd. Since a plate drum B and a holding body Cd are of non compressive quality, the printing pressure is equal to a compressive quality of a rubber type layer constituted with the oil rejecting layer, a photo sensitive layer Cb and an elastic body layer Cc shown in the unshadowed (slant lined) part, and further, it is maintained constant during printing. With this, since ink is compressed in a state wherein it is sealed in a constant partition volume, ink does not overflow from an image position easily, in comparison with an offset printing method in which it is clearly exposed.

For the purpose, obtained evaluated values are gathered by the evaluation areas, the solid bodies are evaluated mutually by the evaluation areas, and a comparison having a large error is not made.

Filed: 1985-07-17
Abstract: PURPOSE:To measure the shape of an object to be measured under non-contact state with high accuracy by grasping relative positional relation between the coordinate system of a measuring machine and that of the object with high accuracy. CONSTITUTION:The coordinates of a measuring point P on the object 6 are found out from the coordinates of a point N indicating the position of an optical point detecting sensor 1, the rotational angles of SW and BD shafts of an angle changing mechanism 2 and a distance measuring value based on the sensor 1. Thereby, the sensor 1 is driven around the object 6 by a three-dimensional driving mechanism 3 and the mechanism 2 and the coordinates of the optical point P are found out by an arithmetic control mechanism at required intervals to measure the shape of the object as a series of points. The shape data belong to the coordinate system of the measuring machine and have no relation to the object coordinate system of design data to be used for automatic measurement, so that linkage operation for finding out the relative positional relation between both the coordinate systems is required. Thereby, a linkage reference shape 11 having the shape information of the object coordinate system is set up on the object 6, the shape 11 is measured as a series of coordinate values of the measuring machine coordinate system and the information of both the coordinate system are calculated to find out the relative positional relation. Consequently, the shape of the object to be measured can be measured with high accuracy.
